Patio doors bridge your interior and exterior. It could be argued that these doors are oversized windows, despite the obvious functional differences and exposure to foot traffic. After all, both are constantly exposed to outside weather, have similar frame-to-glass ratio and mechanical implements for gliding, opening, and locking. Even the installation procedures for window and door replacement in Seattle now require the same skill set.
What sets Renewal by Andersen® patio doors apart from the competition are the energy efficiency and weather resistance that help keep you comfortable in your home, in any weather. We achieve them through:
Our hinged and gliding patio doors in Seattle feature different materials, particularly wood, vinyl, and aluminum. You can be sure that they will be sturdy enough to last long. Our materials also help minimize thermal transfer — a must for energy-efficient installations.
Sunlight consists of:
1. Visible light – The light seen with naked eyes and provides illumination;
2. Ultraviolet (UV) spectrum – The invisible part that causes interior furnishings to fade, among other harmful effects;
3. Infrared spectrum – Another part that carries solar heat, and causes sunburn.
Indoor comfort and energy efficiency depends on how well the patio door glass filters the UV and infrared spectra while letting visible light through. Our sliding and hinged patio doors in Seattle feature double-glazed High-Performance™ Low-E4® glass. The surface of the exterior glass pane features multiple layers of low emissivity (Low E) coating. This lets as much visible light as clear glass does, while filtering up to 95% of UV rays, and up to 74% of infrared.
This makes the heat stays where it counts: inside during the winter, and outside during summer. This in turn means less workload on your HVAC, and more energy savings for your household.
